Filed: 1957-04-30
Abstract: <PICT:0896291/III/1> <PICT:0896291/III/2> An apparatus for applying thermoplastic cement thereto in rod form, comprises workfeeding means, a chamber, and means for progressively melting the rod of cement to provide molten cement in the chamber; a cylindrical roll rotates in contact with the cement to acquire a band thereof on its curved surface, and a rotating applying unit picks up molten cement from the roll at each rotation and applies it in a discrete pattern to the work. The invention is described as applied to a bag-making machine in which a web of paper is rolled to form a tube, the edges are joined by adhesive, and the tube is cut to provide blanks having a step severance.  The ends of the blanks are then pressed by a rotating folding-blade 22 into a variable-width slot 20 formed by a block 15 and the edge 20 of a recess in the periphery of a rotating drum 14.  The block 15 is then moved to grip the folded end and cement is applied to the blank by the cement-coated double edge of an electrically-heated blade 23, the folded end being later pressed by a roller 26 against the cement.  The blades 22 and 23 are mounted on arms which are rotated by the shaft 24, but blade 22 is also mounted for radial movement, and is moved by a roller 88 following cam track 84 so that its edge extends beyond the blade 22 and picks up a coating of cement as it passes a roller 44, but is within the circle swept by the blade 22 as it passes the drum 14.  The roller 44 is coated with molten cement, which is supplied to a chamber 138, the width of the coating which is made available to the blade 23 being controlled by an adjustable metering roll 132, whose periphery is formed with a shallow triangular recess.  The cement is supplied in the form of a rod R, which is forwarded by feed wheels, driven through a friction coupling, through a heated block I to a heated pump unit Y.  This comprises a driven roller 102 having two channels in its periphery, the housing having corresponding passages connected by a cross-passage, and a scraper being provided at the outlet end. The pump supplies the chamber 138 through a passage 100, and a return passage 146 is provided, leading to the inlet side of the pump.  the return channel is normally closed by a pivoted vane 152 and a by-pass valve; but when pressure builds up in the chamber 138, the vane 152 is turned aside, closing a microswitch connected therewith.  This energizes a solenoid 214 which causes a clamp to be applied to the rod R.

[Class 38 (v)] A liquid-break switch comprises a pair of insulated lead-in conductors extending through a cover into a casing with a fixed contact structure connected to the lower end of each, a bridge member for interconnecting the structures and movable downwards to open circuit, the structures and bridge being immersed in the liquid, and an insulating baffle carried by the conductors and extending at least at its edges below the liquid. The baffle is substantially continuous between the conductors and between the conductors and the casing-wall so as to have a confining effect on the liquid-body surrounding the contacts into which the bridge is lowered, and has apertures at opposite edges thereof adjacent and opposite the structures for the immediate and direct escape of gas formed at the structures upon opening circuit. In a simple form, Figs. 1 and 2 (not shown), an insulating plate immediately above the fixed contacts covers the whole space except for cut-away parts adjacent the tank walls and each break, and in order to accommodate excess pressures, this plate may be slidable on the lead-in insulators and have spring control allowing it to yield upwards Fig. 3 (not shown). In Fig. 4, a baffle is located with its plate 27 above the oil level and has side parts 28, 29 extending the length of the tank and under the oil so as to create an air pocket of such dimensions as to prevent oil-throw and to expel the arcgases through passages 281, 291. Alternatively, the side walls of the tank may be made flexible for this purpose. In Fig. 5, (not shown), the baffle is completely immersed and the side walls extend to the contacts, but in Fig. 6, the side walls 31, 32 extend to the bottom of the tank and are apertured at 34, 35 adjacent the breaks to allow egress of gas. Specifications 11448/04, [Class 38], and 371,340 are referred to.
